https://stream.echo6.co/videos/watch/7da1abfc-db6a-494c-b451-a5163cf7725a This video illustrates how RF (radio frequency) standing waves are created in transmission lines - through the addition of the forward (transmitted) wave and the reflected wave that results from improperly terminating the line or matching the load or antenna to the transmission line impedance. I have done several videos that relate to transmission lines, terminations and reflections - all of which tell a piece of the story. This video is another piece, and I hope it helps you to understand how standing waves are formed and what the "look" like. This wikipedia link has some great graphics (shown in my video): https://en.wikipedia.org/wiki/Standing_wave_ratio Here's my video on transmission lines and terminations: https://www.youtube.com/watch?v=g_jxh0Qe_FY Measuring the length and impedance of coax: https://www.youtube.com/watch?v=Il_eju4D_TM How a directional coupler works: https://www.youtube.com/watch?v=byF1FLdbUiA Measure velocity factor of coax: https://www.youtube.com/watch?v=TpIIftvQPFM RF Detector Probe used in this video: https://www.youtube.com/watch?v=C8SKiyJUAlU Brilliant mechanical explanation and demonstration of wave propagation and reflections, courtesy of Bell Labs: https://www.youtube.com/watch?v=DovunOxlY1k ...and if you read this far, here's a challenge... Brownie points to you if you can tell me how I created the "sliding" waveforms and displayed the static standing wave in the first half of the video.
